Samten Migdrön (Tibetan: བསམ་གཏན་མིག་སྒྲོན, Wylie: bsam gtan mig sgron; alternate nomenclature Wylie: rnal 'byor mig gi bsam gtan) is a Tibetan text of historical importance for the historical relationship of Dzogchen and Zen as well identifying the view of its author, Nubchen Sangye Yeshe.
[1] Dalton (2003: unpaginated) in his introduction to the Anuyoga literature of the Nyingma states that: Nubchen Sanggyé Yeshé is renowned for having preserved a number of tantric lineages through the so-called “dark period” of Tibetan history (roughly 842-978 C.E.
107–108) renders an extract of the Samten Migdron in English as follows (Tibetan set in Wylie has been included in References for probity, culled from page 108): "Now, as for expounding the doctrine of Atiyoga, the excellent vehicle, the best and topmost yoga, the mother of all conquerors, its name is the Great Perfection.
Because it gives detailed teaching with a view to imparting direct understanding of the principle of this non-sought spontaneity with regard to all existential elements.
The sense of the spontaneous essence, which is the innermost treasury of all vehicles and the great "universal grandfather" [spyi myes], is to be experienced directly by "self-awareness" [rang rig pas], but not as a thing to be kept in mind.
